Update: After spending the better half of my day trying to figure out when this update would roll out, T-Mobile has removed the support page leading us to wonder if it was posted prematurely. As we remarked below in the main text, today was noted earlier in the week as the available date so we really don’t know what happend or why. Hopefully the update will make a quick return and we’ll actually see it roll out. 

Right on schedule T-Mobile has updated their support forums to highlight a new carrier update for the iPhone adding a host of new and important features. This update was first hinted at earlier this week with a source dropping word to us as enabling LTE on unlocked iPhone devices. As a quick reminder, this update will enable LTE on unlocked iPhone 5 or AT&T unlocked devices with LTE already enabled on iPhone 5 units being sold on or after April 12th.

Let’s just get right to the update which is available as a OTA update or connecting through iTunes:

  • parkpy

    FINALLY!!! I finally have group MMS!! w00!

    Updated mine, but it had no effect. No visual voicemail, no 4G indicator, etc. I’m doing a restore and I’ll report back.

    • http://www.bryanbartow.com bryanbartow

      Restore seems to have done the trick. Visual voicemail, 4G indicator, etc. are all there. Now if only I had someone to test HD Voice with…

  • DVN

    I got the update. However, the LTE (Optional) setting is blank and my connection says only 4G. I’m in Houston TX, shouldn’t I have LTE? If so do I need to input LTE settings to get LTE?

  • Honza

    Got the update! No LTE yet, 4G only. (Boston Metro) Visual voicemail and MMS works great. Had to restart the phone to get everything going.

  • Jonathan Walter Quesada

    i got the update but i did something to get it git it a shot. first what I did was went to carrier then where it says automatic I turned it off after that I went to be about menu and waited about 10 seconds roughly the phone automatically turned the carrier back to automatic and while in the about menu a little message came up asking if I wanted to do a carrier update one down side is that once you do update the update eliminates free tethering therefore it takes away your free personal hotspot

  • Dave

    I have an iphone 4, i got the update and it changed the apn and the carrier, i turned it off and back on but all i got was edge ?

  • 3shan

    I’m only getting edge too but I expected it

    • 3shan

      But I have an i5

    It was a very quick download from iTunes. The Carrier version is now 14.1 on my iPhone. You power off your iPhone and then turn it back on and the features are now on the iPhone. I have an iPhone 4 using a Pay-As-You-Go (non-data) plan. So the in phone voice-mail system isn’t working for me.

    However, I still get the new Voice-Mail screen with a red dot (but no numbers). I just click on the “Call Voice-Mail” button and it dials my old voice-mail system and I access it the same way I normally do. Haven’t tried MMS messaging as yet, but sure that it will work fine, just as all Apple products do.

    Thank you Apple and thank you T-Mobile for all of your support.

    Has anyone actually got LTE yet with this carrier update?

  • nyjumpman23

    It messes up on the MMS messaging on unlocked iphone 4s

  • msohail

    The update is now live … Go to Settings > About on your iPhone to get the update.. Note: the update kills tethering … it also enables LTE, HSPA+ and Visual Voice mail

  • jp2592

    I just manually downloaded the ipcc file and updated it using itunes. I was on carrier 12.0 but now it says 14.1. Rebooting to make sure the changes take into effect. Will report back.

  • natebinsf

    I’m getting 4g on an Iphone4s; however, I’m pissed. The carrier update deleted all my voicemails, 20 or so were from my mom who recently passed. Is there ANY way to get these back?????

    • msohail

      Sorry to hear that .. call T-Mobile … i did the update on my iPhone 5 and it still kept my old voice mails… i hope they can help you retrieve those VM’s

  • Juan Vasquez

    The update disables your hot spot capabilities if you’re on unlimited prepaid plan!

  • Chant

      Bro please this is all bullshit

  • Hec H

    I have a Sprint iphone 4s 6.1.3 with GPP chip on T-mobile network in the USA. The T-mobile carrier update (14.2) does not automatically download to GPP iphones. Anyone try manually installing the T-mobile carrier update hack from itweakios(dot)com to the iphone 4s? Does it work? Did it fix the visual voicemail, hotspot, HD audio, improve data speeds? Anyone up for the challenge?
